Opfindelsen angår en fleksibel beholder til transport og lagring af massegods, og som fortrinsvis er udstyret med en indvendig sæk af et tæt materiale, samt hvis øvre del har løftestropper og en central påfyldningsåbning.The invention relates to a flexible container for transport and storage of bulk goods, which is preferably equipped with an inner bag of a dense material, and the upper part of which has lifting straps and a central filling opening.
Beholderen er anvendelig til massegods i mængder på fra ca.The container is usable for bulk goods in quantities of from approx.
100 kg til flere ton. Den kan være fremstillet af vævede materialer, f.eks. vævet polypropylen, eller lamineret plast eller papir. Den indvendige sæk, hvormed beholderen fortrinsvis er udstyret, kan f.eks. bestå af plast eller papir. Løftestropperne kan være udformet i ét stykke med beholderens øvre del, men de kan også være særskilte stropper, der er fastgjort til beholderen.100 kg for several tonnes. It may be made of woven materials, e.g. woven polypropylene, or laminated plastic or paper. The inner bag, with which the container is preferably equipped, can e.g. consist of plastic or paper. The lifting straps may be integrally formed with the upper part of the container, but they may also be separate straps attached to the container.
I en fra schweizisk patentskrift nr. 362 970 kendt beholder af den angivne art består bunden af trekantede flige, der er dannet ved bortskæring af dele af materialet, og som er sammensyet langs deres kanter, hvilket resulterer i en bund med forholdsvis ringe bærestyrke.In a container known from Swiss Patent Specification No. 362,970, the bottom consists of triangular tabs formed by cutting away portions of the material and which are stitched along their edges, resulting in a bottom having relatively poor bearing strength.
Nærværende opfindelse er imidlertid fremkommet som en videreudvikling af en storsæk ifølge dansk patent nr. 136 765 og norsk patent nr. 136 744. Denne sæk er fremstillet af et enkelt materialestykke, der er foldet dobbelt, og dens bund og sidekanter er dannet ved sammensyning af det foldede materialestykke. Omtrent i midten af foldekanten findes et slidsformet indsnit til dannelse af en påfyldningsåbning, og sidekanterne er syet sammen til et stykke ned fra foldekanten, således at der dannes to løftestropper, der strækker sig fra indsnittet til krydsningspunktet mellem de direkte forlængelseslinier af sidesømmene og foldekanten.However, the present invention has emerged as a further development of a large bag according to Danish Patent No. 136,765 and Norwegian Patent No. 136,744. This bag is made of a single piece of double folded material and its bottom and side edges are formed by sewing together the folded piece of material. About the middle of the fold edge is a slit-shaped incision to form a filling opening, and the side edges are stitched one distance down from the fold edge to form two lifting straps extending from the incision to the point of intersection between the direct extension lines of the side seams and the fold edge.
Denne sæk har vist sig særdeles velegnet til transport af massegods, og den er derhos billig, således at den kan anvendes som engangssæk.This bag has proven to be very suitable for the transport of bulk goods and it is inexpensive there, so it can be used as a disposable bag.

Det har imidlertid ved destruktiv, dynamisk testning vist sig, at fordelingen af belastningen ved løftning af sækken ikke er optimal netop på grund af sækkens bundkonstruktion.However, in destructive, dynamic testing, it has been found that the distribution of the load when lifting the bag is not optimal precisely because of the bottom construction of the bag.
Det er på denne baggrund opfindelsens formål at anvise en beholder af den omhandlede art, hvis bund er således udformet, at den har væsentlig større bærestyrke og væsentligt bedre belastningsfordeling end tilsvarende kendte beholdere, herunder den fra det nævnte danske patent kendte storsæk, og som dog er enkel at fremstille og ikke kræver større materialeforbrug end de kendte beholdere.Accordingly, it is the object of the invention to provide a container of the kind in question, the bottom of which is designed to have substantially greater carrying strength and substantially better load distribution than similar known containers, including the large sack known from the Danish patent and which, however, is simple to manufacture and does not require more material consumption than the known containers.
Dette er ifølge opfindelsen opnået ved, at beholderens bund består af fire parvis diametralt over for hinanden beliggende flige 4, der er direkte forlængelser af beholderens sidevægge, at hvert fligpar i form af ét stykke eller som er forbundet med hinanden, danner en bunddel a,a'; b,b', og at disse bunddele krydser hinanden og er trækbelastelige uafhængigt af hinanden og begrænset bevægelige i forhold til hinanden.This is achieved by the invention in that the bottom of the container consists of four pairs of diametrically opposite tabs 4, which are direct extensions of the side walls of the container, that each pair of tabs in the form of one piece or connected to each other forms a bottom part a, a '; b, b ', and that these bottom portions intersect and are tensile load independent of each other and limited in relation to each other.
Denne udformning af bunden med to, hele bundarealet dækkende lag, der overlapper hinandenr giver bunden en meget betydelig bærestyrke, og samtidig opnås en meget gunstig belastningsfordeling.This design of the bottom with two overlapping layers covering the bottom area gives the bottom a very significant carrying strength, and at the same time a very favorable load distribution is obtained.
En anden udførelsesform, jfr. krav 3, hvor beholderen er dannet af to materialestrimler, der er syet sammen langs kanterne og vinkelret på foldekanten, er ejendommelig ved, at sømmene ender i en afstand fra bundkanten svarende til fligenes længde, og at materialestrimlernes uforbundne ender danner fligene.Another embodiment, cf. Claim 3, wherein the container is formed of two strips of material stitched together along the edges and perpendicular to the fold edge, is characterized in that the seams end at a distance from the bottom edge corresponding to the length of the tabs and that the unconnected ends of the material strips form the tabs.
Herved bortfalder skæring af indsnit til dannelse af påfyldningsåbning og bundflige.This eliminates cutting of incisions to form filling opening and bottom tabs.
Beholderen kan endvidere, jfr, krav 4, fremstilles under anvendelse af en enkelt lang materialestrimmel, hvis bredde svarer til fligenes bredde.Furthermore, the container, cf. claim 4, can be manufactured using a single long strip of material the width of which corresponds to the width of the tabs.

DK 153936BDK 153936B
Endelig kan beholderen, jfr. krav 5, fremstilles af en rørformet materialestrimmel, idet fligene er dannet af snit, der strækker sig tilnærmelsesvis parallelt med rørets langsgående sidelinier og er fordelt langs rørets omkreds ved dets nedre ende.Finally, the container, cf. Claim 5 is made of a tubular strip of material, the tabs being formed of sections extending approximately parallel to the longitudinal lateral lines of the tube and distributed along the perimeter of the tube at its lower end.
Ifølge krav 8 kan bunddelene forbindes med hinanden ved hjælp af fleksible eller svage tråde. Dette tillader, at når beholderen fyldes, vil bunddelene kunne forskyde sig i forhold til hinanden, hvorved der kan opnås en optimal belastningsfordeling.According to claim 8, the bottom parts can be connected to each other by flexible or weak threads. This allows when the container is filled, the bottom portions can shift relative to each other, thus obtaining an optimal load distribution.
Opfindelsen forklares nærmere i det følgende under henvisning til tegningen, hvor fig. 1 viser et udfoldet materialestykke til fremstilling af en fleksibel beholder ifølge opfindelsen, fig. 2 viser en fleksibel beholder ifølge opfindelsen fremstillet af materialestykket ifølge fig. 1, fig. 3 viser et andet, udfoldet materialestykke til fremstilling af en beholder ifølge opfindelsen, fig. 4 viser et rundvævet materialestykke i form af en afskåret slange, hvis øvre åbning danner beholderens påfyldningsåbning, og fig. 5 viser et rundvævet materialestykke i form af en afskåret slange, hvis åbninger er sammenføjet og danner beholderens sidesømme, fig. 6 og 7 viser to materialestrimler, hver til dannelse af en beholder ifølge opfindelsen, og fig. 8 viser en beholder ifølge opfindelsen dannet af den ene eller den anden af materialestrimlerne.The invention will be explained in more detail below with reference to the drawing, in which fig. 1 shows an unfolded piece of material for making a flexible container according to the invention; FIG. 2 shows a flexible container according to the invention made of the material piece according to FIG. 1, FIG.

Fig. 1 viser et udfoldet materialestykke 1 til fremstilling af en beholder ifølge opfindelsen. Materialestykket lægges dobbelt ved at foldes langs den med 2 viste linie. Ved foldekanten 2, der danner den færdige beholders overkant, er foretaget et indsnit til dannelse af en påfyldningsåbning 3, og endvidere er der i hver endekant foretaget et indsnit til dannelse af fire flige 4, hvis endekanter er vist med a, a' , b, b'. Fortrinsvis er indsnittene dannet efter, at materialestykket er lagt dobbelt. For bedre at vise fligene er to af dem skraveret. Dersom beholderen fremstilles med f.eks. otte flige i stedet for med fire, må der være dannet indsnit langs de viste stiplede linier 5 i underkanten. De to sidekanter 6 sammenføjes langs de prikkede linier, og de bundflige, der ligger diametralt modsat hinanden, sammenføjes to og to, således at når der findes fire flige, fastgøres a til a' og b til b'.FIG. 1 shows a piece of unfolded material 1 for the manufacture of a container according to the invention. The piece of material is laid double by folding along the line shown by 2. At the fold edge 2 forming the upper edge of the finished container, an incision is made to form a filling opening 3, and furthermore, at each end edge an incision is made to form four tabs 4, the end edges of which are shown with a, a ', b , b '. Preferably, the incisions are formed after the piece of material is double laid. To better show the tabs, two of them are shaded. If the container is made with e.g. eight tabs instead of four, incisions must be formed along the dotted lines 5 at the bottom edge. The two side edges 6 are joined along the dotted lines, and the bottom tabs which lie diametrically opposite one another are joined together two and two, so that when four tabs are found, a to a 'and b to b' are attached.
Beholderen kan alternativt være fremstillet af to materialestykker, hvis bredde svarer til halvdelen af det i fig. 1 viste materialestykkes bredde, og som sammenføjes langs sidekanterne d - e og f - g, før materialestykket foldes langs linien 2. Skæring af indsnit for påfyldningsåbningen 3 og bundfligene 4 bortfalder, og beholderen får fire lodrette sidesømme.Alternatively, the container may be made of two pieces of material, the width of which corresponds to half that of FIG. 1, which is joined along the side edges d - e and f - g before the material piece is folded along the line 2. Cutting of incisions for the filling opening 3 and the bottom tabs 4 lapses and the container receives four vertical side seams.
Endvidere kan beholderen være fremstillet af et langt materialestykke, og udførelsen bliver da som nævnt foran med fire sidesømme med kun to bundflige 4, idet de to andre hænger sammen, da materialestykket ikke er delt i to. Det vil sige, at a og a' allerede hænger sammen.Furthermore, the container may be made of a long piece of material, and as mentioned above, the embodiment will be with four side seams with only two bottom tabs 4, the other two being interconnected, since the piece of material is not divided in two. That is, a and a 'are already related.
Fig. 2 viser en udførelsesform for en beholder ifølge opfindelsen set i perspektiv skråt nedefra, således at fligenes krydsende sammenføjningslinier 8, 8' ses.FIG. 2 is a perspective view of an embodiment of a container according to the invention, inclined from below, so that the intersecting joint lines 8, 8 'of the tabs are seen.
Fig. 3 viser et materialestykke til en anden udførelsesform for beholderen, hvor foldekanten 2 er lagt i en af materiale 5FIG. 3 shows a piece of material for another embodiment of the container, wherein the folding edge 2 is laid in one of material 5

stykkets lodrette sidekanter. Her må beholderens top sys sammen, hvorved dens bæreevne svækkes noget i forholdet mellem materialestykkets og sømmens strækstyrke sammenlignet med den i fig.vertical side edges of the piece. Here, the top of the container must be sewn together, whereby its carrying capacity is somewhat weakened in the ratio of the tensile strength of the material piece to the seam compared to that of FIG.

Fig. 4 viser en udførelsesform med sædvanlig åben top, fremstillet af et rundvævet, slangeformet materialestykke, men et plant materialestykke med en eller flere lodrette sidesømme kan også anvendes. Til løftning anvendes særskilte løftestropper, der fastsys til beholderens top. Også ved denne udførelsesform sammenføjes fligene to og to langs underkanten, således at a fastgøres til a' og b til b'.FIG. 4 shows an embodiment with the usual open top made of a round woven, tubular piece of material, but a flat piece of material with one or more vertical side seams may also be used. For lifting, separate lifting straps are used that attach to the top of the container. Also in this embodiment, the tabs two and two are joined along the lower edge so that a is attached to a 'and b to b'.
Fig. 5 viser en udførelsesform med et rundvævet materialestykke. Et slangeformet materialestykke med udfladet bredde svarende til beholderens totale højde anvendes. Indsnit for påfyldningsåbningen 3 foretages i midten af overkanten, og indsnit i fligene 4 foretages i underkanten således, at a = a1 = -|b. Langs kanterne a og a' sprættes slangen op, sidekanterne 6 sammenføjes som antydet med stiplet linie, og til slut sammenføjes de således dannede sideflige langs underkanterne a og a', efter at fligene er blevet foldet ud.FIG. 5 shows an embodiment with a round woven piece of material. A hose-shaped piece of material with a flat width corresponding to the total height of the container is used. Incisions for the filling opening 3 are made in the center of the upper edge and incisions in the tabs 4 are made in the lower edge such that a = a1 = - | b. Along the edges a and a ', the hose is opened up, the side edges 6 joined together as indicated by a dotted line, and finally the side tabs thus formed along the bottom edges a and a' after the tabs have been unfolded.
de i fig. 6 og 7 viste materialestrimler til fremstilling af en beholder ifølge opfindelsen er de tværgående, fuldt optrukne linier foldelinier, medens de stiplede linier er sammenføjningslinier. I den i fig. 8 viste udførelsesform for beholderen viser 8 bundsømmen, når materialestykket ifølge fig. 6 er anvendt til fremstillingen, medens 8^ viser bundsømmen, når materialestykket ifølge fig. 7 er anvendt.FIG. 6 and 7, material strips for making a container according to the invention are the transverse, fully drawn lines of fold lines, while the dotted lines are joining lines. In the embodiment shown in FIG. 8 shows the bottom seam 8 when the piece of material of FIG. 6 is used for the manufacture, while 8 ^ shows the bottom seam when the material piece of FIG. 7 is used.

beholderne blev udsat for, var tilkoblet mellem kæden og stativet. Ved testningen fyldtes beholderne med 800 kg styrtgods og blev bragt til frit fald i en udstrækning, der i nedenstående tabel er anført som maksimal faldhøjde, og som altså svarede til længden af den indkoblede kæde. Efter det frie fald blev beholderne følgelig stoppet med et ryk, og belastningskraftens forløb blev målt af målecellen og registreret på en hurtigskriver. Beholderne blev testet, til de begyndte at revne, idet faldhøjden øgedes mellem hver test, indtil beholderen revnede.the containers exposed were connected between the chain and the rack. During the testing, the containers were filled with 800 kg of load and were released to the extent indicated in the table below as the maximum drop height, which corresponds to the length of the coupled chain. Accordingly, after the free fall, the containers were stopped with a jerk, and the progress of the load force was measured by the measuring cell and recorded on a speed recorder. The containers were tested until they began to crack, increasing the drop height between each test until the container cracked.
Maksimum faldhøjde og maksimum kraft angivet i tabellen viser faldhøjde og korresponderende registreret kraft, som beholderen blev udsat for, før den revnede. Bortset fra nogle få tilfælde, hvor der var fejl ved sømmene, brast beholderne ved, at de revnede noget neden for løftestropperne. Det vil sige, at løftestropperne og bundkonstruktionen tåler større belastning end selve materialet i beholderne. De fleksible beholdere var fremstillet af to producenter angivet som type I og type II i tabellen. Dette giver lidt forklaring på spredningen i forsøgsresultaterne.The maximum drop height and maximum force indicated in the table show the drop height and corresponding registered force to which the container was exposed before it cracked. Except for a few cases where the seams were defective, the containers burst by cracking something below the lifting straps. That is, the lifting straps and the bottom structure can withstand greater load than the material itself in the containers. The flexible containers were manufactured by two manufacturers listed as Type I and Type II in the table. This provides little explanation for the spread in the experimental results.

Det fremgår klart af disse forsøg, at den nye bundkonstruktion gør det muligt at udsætte en fyldt fleksibel beholder ifølge opfindelsen for større belastning end den fra dansk patent nr. 136 765 kendte beholder. Beregnet på henholdsvis faldhøjde og registreret maksimal kraft tåler beholderen ifølge opfindelsen 69,1% henholdsvis 43,1% større belastning end den kendte fleksible beholder.It is clear from these experiments that the new bottom structure makes it possible to expose a filled flexible container according to the invention to a greater load than the container known from Danish Patent No. 136,765. Calculated on the fall height and registered maximum force respectively, the container according to the invention can withstand 69.1% and 43.1% more load than the known flexible container.
